Thank you for contacting us.
When I type in your license number ******326 it's saved... but no information is acquired.
Please, make sure that cURL library is installed/enabled on your server: documentation.jomsocial.com/wiki/JomSoci..._System_Requirements
I ask my hosting and this is what i got:
cURL support enabled
cURL Information 7.52.1
Protocols dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtmp, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp Host x86_64-pc-linux-gnu SSL Version OpenSSL/1.0.1t ZLib Version 1.2.7 libSSH Version libssh2/1.4.2
I pass this to our developer for additional check.
I'll update you ASAP.
Please, contact with your hosting support and ask them to help you activate allow_url_fopen = On.
After this it should work fine.
Great to hear that ;)
